Most film buffs would watch anything Christopher Nolan puts out there, and the movie world was abuzz when the first trailer for Dunkirk dropped. However, more than a few eyebrows raised at one name on the cast list: Harry Styles. His fellow co-star Cillian Murphy, however, is insisting that the One Direction member isn't just for hype.

"Harry Styles is great," Murphy told the Radio Times this week. "I had very few scenes with Harry but we got to hang out and I've got to say he's a great, great kid, and really, really funny."

Murphy added that he "trust[s] Chris implicity" for the casting choice:

"Above all, Chris Nolan knows talent and would have cast Harry for a reason. There's a long history of musicians moving over into acting and I come from that world myself, so I'm sure he'll be terrific in the role. I trust Chris implicitly in that."

Earlier this month, Murphy toldEsquire that the crew has been striving to make the film "as authentic as possible." "We spent a lot of time in the actual church where the siege happened," he said. "You could see the real bullet holes, you could see where the grenades exploded. They're all there. It's profoundly moving to walk around there. And our crew was Czech and we had a lot of Czech actors in the film."
